To ai? whom it muy concern.'

Be it known thatI, FRED B. Conor, o citizen of the Unitedl States, residing,l et Scheneci tally, in the conntyof Schenectady, State of New York, have invented Kcertain new and useful Im rovements in Emergency-Brakes, of which t e following is a speciiication.

My invention relates to improvements in means for automatically controlling motors and power-actuated brakes in case of an emergency and is intended for'use es ecially in connection with electrically-propo led vehicles or trains employing,r e braking system actuated by fluid-press To.

relates to improveler.

1g The present invention init-nts 1n the emergency-brake a aratus set forth in my application, Serial o. 148,902, iieri 'March 21, 1903, and comprises various nr -l features of construction end organize,- zn 'non ci parts, to be hereinafter described, and

poriicnisrly pointed out in the claims.

Yin tin" ncroinpsnyin drawings, which illustriic the preferred ein odirnent of my inventii-an, Fiom l is a front elevation of e spef-ii' lo 'if motonc-ontrollcr to which my ini. Jenn applied, the casing-cover h@ wed and certain parte being shown ri Vn .eu-ey end in section. Figs. 2 and 3 srs ecol-inruil pion views on the line 2 of go E, snorting the en'iergency-valve-operoting mechanism in its locked and operative positions, respectively. l1` igw is a sectional pluri i vien' on the lino 4 4 of Fig. l, and Fig. 5 iss.. frzunnmic representation of an "nutoz5 ic nir-broke system to which my invenl I l man muy or applied. 2 Referring now to lthe drawings, A repre sents the luci( of n n1otor-controlier casing, I anni E the operatingdmndle for the eontrollera i cylinder il within seid casing. The control ,f ler-cylinder i3 carries the usuel Vcontact-segments fiend is geared by oog-wheelsUC ion E sha-ft l), wlliel' runs up into the huh c of the .l

' operating-handle E. l

he huh is rotatable in l nn opening in thc cuploic A of the easing i and is fastened to the s oft l.) hy ineens of a setscrew d.

Rotatehl f mounted on the shaft l) is e. sleeve F, helld yieldin ly inits normal position by a helical spring l* which is connected et' cnc ond to the sleeve and at the other end to the shaft D, preferably by means of s collar D', secured to said shaft. The sleeve F carries a camfend lugg, Figs. 2-and 3, the letter serving es o stop y abuttin againstostaai-g tipnory lug o on .the under si e of the 'oep` ate. 'Y p Connected with the knob E in the controilcr-handle is a pin e', which rests upon the long arm of the lever E1, fulcrumed on the o meting-handle E. A spring E bears on the short arm of the lever and keeps the pin and knob normally raised. A toothed rocker E* also is ulcrumed on the operatie handle and en ages with the short arm of t e lever E. T e other end of the rocker E* engages with a lng on s. bolt G, slidnble in a keywe in the shaft D and adapted to enter s. noto in the upper endl of the sleeve F and lock said sleeve to the shaft. This will occur Whenever the knob E is depressed, provided the controller-handle is in the position correspending to the off position of the control- The sleeve F is adapted to be rotated witn the shalt D so long as rassure is maintained on the broad knob on which the palm of the xnotormans han is adapted to rest while the oontrollenhandle is being operated.

Adjacent to the shaft D within the controller is a rock-shui' t H carrying en erm k, which hears against the calnf, as shown in Figs. 2 and 3, whereby the movement of the sleeve l" will rook the shaft H. Mounted on the shaft ll is an erm it', carrying a block of insolution H', on which ere mounted two connec tcrl spring pontsebngers, which cooperate with stationery contacts end form therewith a. double-pole switch I for closingr und openi the power-circuit when the shaft H is rocke RS represent the roversingswitch, W an interiociring device between said reversingswitch and the shaft l), end Lindientos the insnloting-cosing containing the blow-out coil for the switch I. y.

Mounted within the controller-casing and operatively connected in the air-brake systern is on einer eney-valve which is ada ted to apply the bra es 1n oase the oontroilerandle is relesedin any of its operative pos tions. To epy the brakes when the socellefi automatic air-brake system is employed, the emergencyvulve exhausts the tram-pipe to atmosphere, and when the soviillvd "traight stir-broke s vstvin is mployvd it vonnvcts thv sourov ot' i'iniipi ssvil lhiid supply to saidtiiiiii-pipv,

9. In combination, a controller having a shaft und an operatinglmiidle, u power-notuiited brake, ii brake-controlling device, a

:"o member loosely mounted on said shaft for operatingr seid brake-controlling device to reuse the hiakes to he applied, means for eotuuting seid member, ineens for looking Said member to said shaft, said letter means be- 15 ing,t arranged to unlock said member from the shaft when the controller-handle is released and a device for movin said member on said sha1' t'to release the braio-controlling means, the arrangement being suoli that the means for locking said member to the shaft is made zo inoperative to a ein perform its lookin function udtil said latter device is operate to move the said member into brake-releasin position.

n witness whereof I have hereunto set my 2 5 hund this 19th day of March, `1903.
